OpenChart brings AI agents into every step of your investment journey: statistical and technical analysis with code and charts, real-time responses to market events with alerts, opportunity discovery through agentic research, and more. OpenChart is not built to monetize software, but to explore a future where humans and agents manage assets together. If you believe in this future and want to join forces, [we want to talk to you](https://discord.gg/PR4gfbMKUD). ## Quick start [Download Desktop for macOS (Apple Silicon)](https://downloads.longsurf.ai/openchart/darwin/arm64/OpenChart.dmg), open the disk image, and install OpenChart. To run Desktop from source, install [Node.js 24](https://nodejs.org/en/download), [npm 11.11.1](https://docs.npmjs.com/downloading-and-installing-node-js-and-npm/), [Bun 1.4.2](https://bun.sh/docs/installation), and [Just](https://just.systems/man/en/), then run: ```sh git clone https://github.com/longsurf-ai/openchart.git cd openchart just install --frozen-lockfile just desktop ``` `just install` also initializes and builds Tea, a programming language built for analyzing market, by the same team. Follow the [setup guide](https://openchart.co/docs/getting-started/) for your first chart and alert, or the [development guide](docs/development.md) for building and packaging the app. Desktop is free. AI usage follows your agent provider's plan; optional Cloud market data is priced separately. ## Key features

Charts without software quotas

Add indicators and Volume Profile, then expand to a 4×4 grid. No software plan limits on charts, indicators, or price and indicator alerts.

Use your own agents

Use your Claude, Codex, and Gemini models to research markets, build indicators, and set up alerts with the accounts you already have.

A plain-language request becomes Tea monitors and an alert that asks Codex to investigate an illustrative market move.

Describe what to watch

Tell your agent what matters. It builds Tea monitors that evaluate incoming data and investigate when a condition fires.

Select a chart range, research the move, and expand annotations with linked sources.

Explain what moved the chart

Select a range and let your agent research the move, with source-linked annotations pinned to the bars.

Draw a wedge, create an alert, and watch a breakout trigger agent research in this illustrated workflow.

Draw it, get alerted

Draw a line or zone on the chart. When price crosses it, an alert can ask your agent to research the move.

Write your own market logic in Tea

Build custom indicators and conditions with functions, loops, state, and collections that evaluate as data flows in. Explore Tea →
